Abstract

The invention consists of the use of a screw (1) much shorter than the traditional one, engaged with a plug (2) of silastic or any other polymer having equivalent mechanical properties and biocompatibility, metal or metal alloy. Said plug is inserted in the pedicle (8), extending only slightly beyond the length thereof. The system is applicable to osteoporotic patients in whom the density of the bone tissue of the vertebral body is much lower, and in general in all lesions of the backbone in which instrumented vertebral fusion is indicated. <IMAGE>
